Extensive Definition

Globulin is one of the two types of serum proteins, the other being albumin. This generic term encompasses a heterogeneous series of families of proteins, with larger molecules and less soluble in pure water than albumin, which migrate less than albumin during serum electrophoresis.
It is sometimes used synonymously with globular protein. However, albumin is also a globular protein, but not a globulin. All other serum globular proteins are globulins.
Protein electrophoresis is used to categorize globulins into the following four categories:
globulin in Arabic: غلوبيولين
globulin in German: Globuline
globulin in Japanese: グロブリン
globulin in Macedonian: Глобулин
globulin in Polish: Globuliny
globulin in Portuguese: Globulina
globulin in Slovenian: Globulin
globulin in Finnish: Globuliini
globulin in Swedish: Globulin
globulin in Thai: กลอบูลิน
globulin in Turkish: Globulin
